   4 Subject: net/mlx5: Allocate root ns memory using kzalloc to match kfree
   5

   8 [ Upstream commit 25fa506b70cadb580c1e9cbd836d6417276d4bcd ]
   9
  10 root ns is yet another fs core node which is freed using kfree() by
  11 tree_put_node().
  12 Rest of the other fs core objects are also allocated using kmalloc
  13 variants.
  14
  15 However, root ns memory is allocated using kvzalloc().
  16 Hence allocate root ns memory using kzalloc().
